Japan's First Baby Shark Collaboration Rooms Open at Ryugujo Spa Hotel Mikazuki Ryugutei in Kisarazu, Chiba

Ryugujo Spa Hotel Mikazuki Ryugutei in Kisarazu, Chiba, has opened "Baby Shark Rooms" in November 2026, created in collaboration with Baby Shark (Pinkfong Baby Shark), a character loved by children around the world and known for ranking first in YouTube views worldwide. The rooms were developed with The Pinkfong Company, a global family entertainment company.

The new rooms are a limited lineup of three special rooms, renovated from the hotel's previous Baby Rooms. With the world of Baby Shark filling the guest rooms, the space feels like stepping into the sea, and the whole family can enjoy a special hotel stay together.

The rooms keep the safety features for small children that the previous Baby Rooms offered, and have been reborn as collaboration rooms that make a family stay even more fun.

These are the first Baby Shark collaboration rooms at an accommodation facility in Japan.

A Special Family Time in the World of Baby Shark

Colorful and cute characters from the "Baby Shark Family" appear throughout the rooms. The world of Baby Shark is woven into the walls, interiors, and other details, creating a space that excites children from the moment they step inside.

The rooms are designed for children who love Baby Shark, and also for the whole family to enjoy together.
